"The Talk" this week has been about sharing the co-hosts' quietly kept secrets, and Sara Gilbert opened up with one involving a former "Roseanne" co-star.

When Gilbert, now 38, was starring on Roseanne Barr's '90s comedy as Darlene Connor, she was also dating her co-star Johnny Galecki, who happened to play her on-screen love interest, David.

But that's not the secret (as Gilbert says, some "Roseanne" fans probably already knew that). Here's what she spilled:

"I thought he was super-cute and had a total crush on him and we started dating (as teens)," Gilbert recalled. "And he would come over and we would like, make out, and then I would start to get depressed."

Becoming emotional, Gilbert explained that Galecki began to feel badly about her reaction and was taking it personally, "so I eventually told him that I thought it was about my sexuality, and he was super-sweet about it."

When Gilbert began to date a woman 18 years her senior while doing "Roseanne," Galecki helped her keep the relationship under wraps.

"(She) was also in the public eye, it was something people really could've found out about," Gilbert said. "No one knew at the show for years, and Johnny held the secret the whole time. And I just felt ... always so scared if it came out, what could happen. Would I lose my career, would I ever be able to play a straight role again?"

"When I talk about my sexuality on the show, or in public, I still feel really scared. ... There's still a piece of me that goes, what is this costing me in my career?" Gilbert said. "I want people to know that we often say things like, 'It gets better,' and it does get better, but I want people to know that, I guess, that there can still be a struggle with it and that's OK. It really is a process, and there can be a part of you that doesn't want to feel different or feel scared."

Thankfully, Gilbert has friends like "Big Bang Theory" star Galecki to support her. The actress said she called Galecki prior to sharing her secret to make sure he was OK with it, and he gave her his blessing.

"He said, 'I love you and I think it's really important and I'm so proud of you," Gilbert said, adding that he even offered to come on the show with her and hold her hand.

My uncles see my mother as their own...if you do not like your mother in law then go handle it hon...instead of mother in law issues and s-x...she's here...If he tolerates your mother in law issues....good for him.

I cannot tell you how many men I dated that I either could have gone gay on or thought I was gay. Come on. You don't just all of a sudden "realize" that you're gay. That's like a black man at the age of 14 waking up one day and saying to himself, "Hey! I'm black!" You either are or you aren't. Being gay is a choice that's why she made that choice while dating this Johnny. She "realized." Otherwise she would have been born, her parents would have said, "Honey? Now remember, you're gay." You don't just DISCOVER it. Being gay is a CHOICE people.

Yes! being gay is a choice. just like being stupid is a choice. I choose to contradict myself by saying being stupid is a choice. thats why when I was 14, I woke up one day and discovered I was stupid. I chose to tell my parents so they would remind me that I was stupid just in case I ever said anything smart. Its a choice people! you either chose to be born stupid or you chose to be born smart! Everything is a choice. Tomorrow I will choose to be an 85 year old korean mechanic. and the next day I chose to be Oprah. Life is great!

Damn it, life is really complicated. I remember watching these two on tv when I was a kid. It's sad that instead of just having a romance as I thought they were off screen, she was hiding in the closet terrified and he was keeping her secret. And how are we all to react to it? We're now all treated as bigots if we don't think of her coming out as great. What can be said though, finding out everything you ever thought was one way, was another, is hard. I wish these two people I thought were so happy hadn't been miserable.

get the IP for 3d and let's complete virus check.....what the fk do you tell people....your illegal we know that
and you owe me 8 grand for busted comptuers.....who the fk are you? trailor trash that's about

at some point in their lives...you not OUR kind...we don't have too be YOUR kind. We do not want young career women with kids following your way. We don't know you therefore your considered a bully–anyone who follows your path we are very concerned about and we will make sure women do no go this way.

Your technoology stinks. Any MAN who follows you path we wonder about also..... i grew up with gangstas but they were good at it. Your just a bimbo with bad tek, we are number 1

Dont really mind if some ones gay or not, thats their business. Just wish people like Ellen and rosy O would quit ramming their choices down my throat like they are demanding my appoval. Just be gay and have a good life, I dont care, dont want to know thank you very much.

thats what I said...I m sick and tired of this gay stuff everywhere...No one cares..and the fact that they keep pushing and shoving it as you said in everyones face is actually making annoying..If someone is gay ..ok Im straight ..pls enough of this stuff..I m tired of hearing about it and seeing it.Stop forcing us to acknowledge it.thank you and enjoy life!

Oh please, I could tell she was gay when she was on Roseanne–if she did not know it–it was obvious. And who gives a poop? Do what yo want, makes no difference to me. Just wish you weren't so damn dumb.

So so very sick of this twit. She carried a public pity party when her woman dumped her, now it comes down to one again using the audience as her emotional tampon. She's a user, she's selfish, no wonder she's a perfect fit for The Talk.

I've been putting this off for years because I wasn't sure how some people would react, but I have to be true to myself so here goes: I'm straight. Please don't judge me, I was born this way. I can't help who I love. It doesn't make me a bad person.

If this announcement did not shock or offend anyone, neither should someone being gay. Live and let live.

All the synical, sneering little evil b!tches on here should have a long hard think about themselves and how they behave towards others. It is unbelievable in today's day and age that a simple human interest story about a respectable actress would receive such vitriolic spiteful remarks as is seen ojn here. You should all be ashamed of yourselves for being such small minded little gossips and arrogant selfish bas-tards. Shame on you all.

You speak the holy truth. One day, Star Wormwood will emerge, Jesus will return, and the heavenly fire will rain down upon the unclean. The streets will run slick with liberal blood and the archangels shall have their holy vengeance.

Because 50 is a good person no matter what your clowns think....it does not matter because majority rules and even if you bash me they won't believe you because they know me and they know I won the hacking game well over a year ago. I do no need too do vicious behavior too anyone i will defend myself legally because i am always right.

i have the personality and that is why EVERYONE responds too me. I had it then, I have it now and i will have it until I die. I have the personality and i'm not a hacking bully who does not know its ass from its elbow.

I went on a date and discovered that I was a concrete block. Does that mean it's true or does it mean I'm insane? See my point? This, "I discovered I'm gay," thing not only arbitrary, it is total bull shlt with a capital stinks badly!

Interesting how you turned someone saying "I dont care" into hate. Calm down a little bit, breath and then try to read what people are actually saying before you blow a gasket. Being completely unconcerned with something means just what the word unconcerned implies....that some of us simply dont care. That doesnt mean we hate anything. To hate would be to care greatly which isnt the case at all. I get that you are angry. There are some folks who actually hate gays. Can you please spew your hatred toward them and leave those of us who are simply tired of watching the battle alone? Thanks a lot.

I wasn't upset about the i dont care part. I was mad that someone writes "why do gay people always have to tell everyone about it" as if we should just not exist. There's a reason people feel passionately about this issue and it is because some of us have had to battle our whole lives to prove that we are "normal" functioning parts of society and not all pedos or sick freaks. You seem to have no concept of that though with your "dont care, doesnt directly invole me". Well WHY DID YOU CLICK ON THIS ARTICLE AND READ IT THEN? IF gay people are so unimportant, just skip the f-cking story.

OK she was on Rosanne and she was worried about a career? Am I missing something? Sometimes women think they are gay then en up marrying/loving men. Or visa versa. Not to say it's not hardwired but it seems a bit personal choice and keeping it under wraps? Who give cares? .

15-20 years ago, it was a lot different. While "coming out" for an actor/actress might be significant for the person, it is not "shocking" or even really that noteworthy to society. 20 years ago, it would have been. That is what she is referring to.

Remember how a primary issue for GWB in the 2004 re-election campaign was "gay marriage" and he really emphasized this issue in Ohio, which turned out to be the "battleground state?" It was such an important issue then – and that's only 9 years ago. Now, it really isn't.

What a bunch of disgraceful bigots we have here with us on the Marquee Blog. I really hope some of the comments below are people just trying to stirr up anger by trolling fake opinions, because if that is really how people in the US think, you guys are not as free and progressive as you think. Absolutely discusting.

"David" was so cool on screen and I loved his Rosanne character much. I am so not surprised that Mr. Galecki is such a dear and true friend in real life to Sara. They are hard to find and I wish Ms. Gilbert all the best and hope she continues to find happiness in her life today and always.

I'll try this again...
How disturbing that so much of Hollywood is so screwed up and they have so much unhealthy influence on young, impressionable kids today! I wish there was some way that they could just do their acting and keep their opinions and lifestyles to themselves because, despite their best efforts to project it, Hollywood IS NOT a pure microcasm of American society!

What you're forgetting is that any "microcosm" of society-even outside of Hollywood-includes gay people. And whether you like it or not, gay people will continue to be born and will continue to exist. Be more tolerant. (Amen to that).

How disturbing that low-IQ commenters on CNN can't keep their discriminatory opinions to themselves. So many low-IQ people find it necessary to make negative comments about people who live their lives open and honestly. They were prefer that their children be told lies, and that their children are taught that they will not be loved if they are different.

You are a terrible human being, kenman. No, Hollywood is not a microcosm of American society - there are a LOT more gay people in the real world than you see on TV.

I know you also feel that it's terrible that we show black people on television. It's horrible that Hispanics are shown living normal lives. And don't get you started about how women are allowed to vote and have opinions. That's just the worst. When you say bad things about one group of people, you are saying them about everyone.

Very proud of Sara and Johnny. Not ever one is the same and what a friend to keep information to himself. The rest of you that are haters. Wonder if you'd be such a hater if a gay person was the only one that could save your child's life.. would you say no then? No, you wouldn't, you'd be on your knees begging that person to help you. It's funny where a person moral compass lives....usually buried so deeply they don't pull it out until it affects them or the ones they love. With that said.. Rock on Ms. Gilbert –the world truly does love you. And haters, rock on as well–the world loves you as well even though you seem not to love it back.

I went to a university with a large lesbian/gay community. There were plenty of women who "discovered" they were gay after a bad relationship with a man. I talked to one on them, years later. She'd been married, and barely even remembered her "gay" phase.

Well their goes (their) theory that gays are born that way. It has been my observation that most lesbians are that way partly because of their relationships with other men (either abused, raped, no father figure, divorce). It's a cop out. According to the LGBT community you are either gay or you're not and that's it's from birth.

Ilroy, what do meann by "it's a copout"? Why do you seem to have evidence and information that no study or scientist has ever been able to prove? Oh, wait, I get it, you don't like gay people so you assume that something bad must've happened to them to "cause" their gaynesss (with no evidence of this). What about all the gay people from "normal" "healthy" families then? How did they "become" gay then Mr-expert on gay people? I bet you've never even had a gay friend.

I always thought Johnny was so cute. I loved him on Roseanne (and I hated the way Darlene treated him most of the time.) It makes me happy to know that he is a good guy in real life and that they have such a close relationship. I never knew they dated during the show. (I don't usually pay much attention to these things).

Can the moderator of this site stop the SINGLES DATING SERVICE ? is kind of annoying ,this is to chat not to put a ad! it is obnoxious really! why this people doesn't put this kind of ads in somewhere? is kind of free advertisement isn't ? or they paying for it? not matter what it is annoying indeed!

He has to be nice and civil, the PR's let them now how to act and be positive ...what a shame leave a man for another woman whaoooooo, it has to affect their manhood I think! like this actor who's wife left him for another woman ! but this guy is very handsome guy I see him often in Big Bang Theory he is just short guy.....

I'm really glad she had such a good friend to talk to. Too bad she was scared to be herself. I've said it before, I'll say it again...if we were all the same, it would be a boring world. Don't let people knock you for who you are. If they don't like it, tough sh it!

Would your truck be called big blue, by any chance. There's this guy on the foodie blog who goes by the name of Richard Head, who has a remarkably similar story as yours. Hmmmm! Richard Fore/Richard Head. Pretty similar. Foodie blog get too boring, and you decide to come over here? Just do us a favor, leave Observer over there. That person is an azzhole.

If you watch the shows, movies, commercials, etc. BLACK men don't want black women either. But,then again, if you look at the popular depiction of black women, like the obnoxious character the cross-dressing Tyler Perry plays, you can clearly see some reasons for that!

Whoa dude! Take Beyonce, Halle Berry etc. anytime. . I think most white males aren't attracted to big butts and chunky type bodies of any race- the sterotypical black woman.- and that is a choice. Check any society and see what the current ideal of beauty is, check back 300 years and you'll find a huge difference
